Ten analogs of muscimol and thiomuscimol in which the amino function was delocalized in an amidinic system were prepared by N2 alkylation of 6-aryl-3-aminopyridazines with (chloromethyl)isoxazole or (chloromethyl)isothiazole derivatives. These muscimol and thiomuscimol derivatives show potent binding properties for GABA-A receptors (they displace [3H]GABA and [3H]gabazine) and provoke convulsions after
通过将6-芳基-3-氨基哒嗪与(氯甲基)异恶唑或(氯甲基)异噻唑衍生物进行N 2烷基化反应,制备了氨基官能团在local胺基体系中离域的十种麝香酚和硫代麝香酚类似物。这些muscimol和thiomuscimol衍生物显示出对GABA-A受体的强效结合特性(它们取代了[3H] GABA和[3H] gabazine)并在静脉注射后引起惊厥。它们与我们小组提出的GABA-A拮抗剂模型药效基团非常吻合,并显示出与哒嗪基-GABA相似的结构活性图谱。
